Think like a supervillain. Now build a vignette (min. 8 x 8, max. 24 x 24) with a clever trap to catch a superhero of your choice. The more absurd, complicated and funny your trap is, the better. A reasonable(!) overhang is allowed, like a plant, arm, leg, etc. A one stud wide black base around your creation is allowed. It counts as overhang.

This model represents a trap by the Joker to catch Batman. Here is how the trap works:

1. A Robin dummy lures Batman into a dark alley.
2. Robin's bonds are disguised electric shockers. If Batman attempts to free Robin he will be zapped unconscious.

3. If Batman for some reason does not start grabbing Robin's bonds (perhaps he saw the huge Joker face drawn on the wall), the Jack-in-the-boxs should spring up and attack.

4. If Batman gets scared and attempts to escape by air, he will be cut off by henchmen floating on balloons.

5. If Batman gets scared and attempts to escape in a different way, he will probably get away.

4th wall commentary: This was a relatively simple and unoriginal build, but it was fun and I hope everyone likes it.
Here is a closer look at the Joker's grafitti.

Very good; better than I could have. Somehow I don't like this very much though. It just seems a bit plain with that large open space in the center of the alley. And It doesn't seem much like an alley either. Nice work, just not your best in my humble opinion.

I agree with you that this isn't my best work and that it does not specifically look like an alley.
